Description

The Brain Nebula!!

I know its been a while but ive been feeling a little burnt out due to another failed astro project i was working on with over 40 plus hours of data (My usual going integration). To get back into the groove I will just explore for now..........

I am now christening Earths Galactic Nebula Season with the Brain Nebula (NGC 6888)

The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.
